Who is Dart?

Dart machinery started in a humble environment. Dart was founded in Oak Park, Michigan, in 1981 in a two-car garage. Dart has developed into an established pioneer in re-market cylinder heads, intake control systems and motor blocks throughout the years after the company started a business using a desk and telephone.

Dart's Commitment to High Quality?

Dart is committed to assembling the best engine components available. All development, machining, and assembly are accomplished at Dart facilities to keep the highest quality measures. CNC, a computerized dynamometer, and the proprietary Maskin are updated to the state of the art technology advancement in the Dart engine production program. Engine program and daily interaction with leading engine builders and winning racers put Dart on the leading edge of technology

The original company products were aluminum Hemi cylinder heads that controlled the top fuel and funny car levels. These purpose-built heads granted the power that ultimately broke drag racing’s 300 mph barrier and designed the first four-second Funny Car elapsed time. In recent years, Dart spread-port Big Chief heads have set the measure in classes ranging from Pro Street to Pro Mod. The launch of the inexpensive Iron Eagle and the PRO 1 cylinder heads for large and small Chevy V8s, backed by aluminum- and cast-iron engine parts, is also continuing this tradition of innovation. Dart considering expanded its product line to include small-block Ford and Honda parts.
